Load Based Speed Control or LBSC is an electronic feature that is programmable on the Cummins ISX15 and ISX12, and ISX12 G engines. LBSC encourages the driver to shift into the next gear as soon as possible and is active in all gears except the top two. LBSC turns off when applications are above 100,000 lbs GCVW, during tire scrub events, and when grades exceed 2%. To set up or adjust LBSC trim settings, download PowerSpec, a free computer application, and talk to your local Cummins representative to receive free licensing rights. For more information, visit the feature description section of cumminsengines.com/powerspec.
